Healthy living is a life style and knowledge is key. With this in mind, we wanted to explain the different blood types and who you can donate to.

Although our blood is made from the same elements, there are eight different blood types, which are distinguished by the presence of substances called antigens, which activates immune responses if they are foreign to the body.

Some antigens can attack transfused blood, so it is crucial to consult a health practitioner or qualified expert for safe blood transfusion, blood typing, and cross matching.

There are four groups of blood, which are identified by the presence or absence of two antigens on the surface of red blood cells called A and B.

Group A: Has only the A antigen on red blood cells (B antibody in plasma)

Group B: Has only the B antigen on red blood cells (A antibody in plasma)

Group AB: Has A and B antigens on red blood cells (neither A nor B antibodies in plasma)

Group O: Neither A nor B antigens on red blood cells (both A and B antibodies in plasma).
